Why this page exists

Risk in Maine is not one thing. It depends on where you are.

Maine stretches 320 miles from Kittery to Fort Kent, and the hazards that matter to a household in southern York County look nothing like those facing a household in Aroostook County. A coastal family prepares for storm surge, erosion, and nor'easter flooding. An interior family prepares for ice storms, extreme cold, and roads that close for days. A household anywhere in the state prepares for extended power outages, because Maine's heavily forested landscape and long transmission lines make multi-day outages a structural condition, not a rare event.

This page helps you identify which hazards and disruptions are locally relevant, understand how risk changes across the state, see which times of year deserve closer attention, and build a household plan around what is actually likely where you live. It focuses on warning systems, household continuity, cascading failures, and recovery. For land, water rights, growing conditions, and property due diligence, see the main Maine guide.

The main Maine land and self-reliance guide covers the statewide score, land-search regions, water law (absolute dominion for groundwater, reasonable-use for surface water), food sovereignty ordinances, right-to-farm rules, growing conditions, the true cost of raw land, a parcel checklist, and insurance. This Local Risk guide focuses on warning systems, household disruption, continuity, and recovery.

Start here

Identify your local jurisdiction and forecast office.

Maine has 16 counties and nearly 500 cities, towns, and plantations. Emergency management, alert enrollment, and many hazard-specific services are organized at the county level, with a county Emergency Management Agency (EMA) in each county coordinating between local communities and the Maine Emergency Management Agency (MEMA). Knowing your county and the National Weather Service office that covers it is the starting point for every other decision on this page.

Find your county emergency management

Each of Maine's 16 counties has a county EMA that coordinates emergency preparedness, response, and recovery for local communities.

Find your NWS forecast office

Enter your address at weather.gov to find which NWS office issues warnings for your area. Maine is covered by two in-state offices.

National Weather Service

NWS offices serving Maine

Caribou (CAR) — northern and eastern Maine including Aroostook, Piscataquis, northern Penobscot, Washington, Hancock, and northern Somerset counties
Gray/Portland (GYX) — southern and western Maine including York, Cumberland, Oxford, Franklin, Androscoggin, Sagadahoc, Lincoln, Knox, Kennebec, Waldo, and southern Somerset counties

Statewide baseline

Ten preparations that address several Maine hazards at once.

These preparations apply regardless of where in Maine you live. Each one addresses multiple hazards rather than a single scenario, and most are free or low-cost.

Redundant warning methods

Enroll in your county's alert system, keep a NOAA Weather Radio with battery backup, and enable Wireless Emergency Alerts on every household phone. No single channel is reliable in every scenario.

Backup heat independent of the grid

Whether you heat with oil, propane, electricity, or wood, identify and test a backup heating method that works without grid power. This is Maine's single most consequential preparation.

Stored water (and well pump awareness)

Store at least three days of drinking water. If you depend on an electric well pump, a power outage is a water outage. Gravity-fed spring systems and hand pumps are exceptions worth understanding.

Backup lighting and device charging

Headlamps, lanterns with extra batteries, and a way to charge a phone. During multi-day outages, battery-powered light and a charged phone are the difference between isolation and information.

Route planning with alternatives

Know your primary and alternate routes to the nearest hospital, pharmacy, and supply point. Maine's rural road network means a single washout or downed tree can close the only road in or out.

Medication continuity

Maintain a current medication list and keep copies of prescriptions in a portable location. If a medication requires refrigeration, have a plan for maintaining cold storage during an outage.

Household communication and reunification

Establish a family communication plan with an out-of-state contact. Agree on a meeting point if household members are separated when an event occurs.

Fuel reserve

Keep vehicle fuel above half during higher-attention periods. If you use heating oil or propane, schedule delivery before storms rather than after, when delivery trucks may be delayed for days.

Records and insurance documentation

Keep copies of insurance policies, identification, and critical household documents in a waterproof portable container. Standard homeowner policies do not cover flood damage; verify your coverage separately.

Pet and livestock arrangements

Include animals in your planning. Livestock water systems that depend on electricity need a backup. Pets need carriers, food, and medication packed for a possible evacuation.

Hazard profile

What can happen, where it matters, and your first decision.

The 2023 Maine State Hazard Mitigation Plan classifies nine Tier 1 hazards: flooding, severe summer weather, tropical cyclone, severe fall/winter weather, wildfire, drought, erosion, mass wasting, and earthquake. The table below focuses on how each translates to household disruption and what you do about it.

Maine hazard-to-disruption decision table
Hazard or condition Where it matters Higher-attention period Warning character Likely household disruption First planning decision Full guide
Ice storms Statewide, heaviest impact interior and southern November through March 12 to 48 hours advance notice typical Extended power outage (days to weeks), road closures, heating loss, water loss for well-dependent households Establish backup heat and test before winter Ice storm checklist
Nor'easters and blizzards Statewide; coast gets wind and surge, mountains get snow, interior gets ice October through April 2 to 5 days advance tracking; 3 to 5 major events per winter Road closures, power outage, coastal flooding and erosion, school and business closures Plan for multi-day road closure and power loss simultaneously Winter storm checklist
Extreme cold Statewide; most severe in Aroostook, Piscataquis, northern Somerset December through February Wind Chill Warnings issued with 12+ hours lead time Pipe freezing, heating system failure, frostbite risk, vehicle failure, delivery disruption Insulate pipes in vulnerable areas; maintain fuel reserve measured in weeks Winter storm checklist
Riverine and flash flooding Kennebec, Penobscot, Androscoggin, Saco, St. John, Aroostook, and Fish River valleys March through May (snowmelt); also tropical remnants (Aug-Oct) Flash Flood Warnings may arrive with under an hour of lead time; river floods develop over days Road and bridge closures, basement flooding, well contamination, evacuation Check whether your home and travel routes cross a mapped flood hazard area Flood checklist
Coastal flooding and storm surge York, Cumberland, Sagadahoc, Lincoln, Knox, Hancock, Washington coastline October through April (nor'easter season); tidal flooding year-round Coastal Flood Warnings; highest risk when storm surge coincides with astronomical high tide Property damage, road flooding, saltwater intrusion into wells, beach and bluff erosion Review Maine Geological Survey storm surge and sea-level-rise maps for your property Hurricane checklist
Extended power outage Statewide; most prolonged in rural areas served by long transmission lines Year-round; worst November through March No direct warning; follows other hazards Loss of heat, water (well pump), refrigeration, communication, medical equipment Identify every household system that stops working without electricity Power outage checklist
Wildfire Statewide; 89% forested (17.5 million acres) April through June (spring fire season); late summer during drought Red Flag Warnings; fires can develop rapidly during drought and wind Air quality, evacuation, road closure, property loss at wildland-urban interface Maintain defensible space around structures; know your evacuation route Wildfire checklist
Severe thunderstorms Statewide; most frequent in southern and western Maine May through September Severe Thunderstorm Warnings with minutes of lead time Damaging wind, localized flooding, power outage, occasional tornado Identify your lowest interior shelter location Thunderstorm checklist
Drought Statewide; greatest household impact on private-well households July through October Gradual onset tracked by U.S. Drought Monitor Well drawdown, burn restrictions, increased wildfire risk, crop and garden loss Know your well depth and historical yield; conserve early Drought checklist
Earthquake Statewide at low levels; higher activity near Passamaquoddy Bay, Dover-Foxcroft area, Portland-Lewiston region No seasonal pattern No advance warning Most buildings not designed for seismic loads; likely limited to chimney and masonry damage in a significant event Secure heavy items on shelves; know Drop, Cover, Hold On Earthquake checklist

Operational risk regions

What you prepare for depends on where in Maine you live.

These operational regions group areas by shared hazard exposure and infrastructure characteristics, not by political boundaries. They are different from the land-search regions in the main state guide, which organize around property suitability.

Southern Coast (York and Cumberland counties)

Maine's most densely settled area and most vulnerable to coastal flooding, storm surge, and sea-level rise. The southern coast from Kittery to Portland faces recurring nor'easter damage, tidal flooding, and accelerating beach erosion. Urban and suburban infrastructure provides faster utility restoration but higher population density during evacuations.

Hazards requiring added attention: Coastal storm surge, tidal flooding, beach and bluff erosion, severe thunderstorms, urban heat

Likely complications: Evacuation route congestion on Route 1 and I-95, saltwater intrusion into coastal wells, combined sewer overflows during heavy rain

Three local verification tasks: (1) Check the Maine Geological Survey sea-level-rise map for your property (2) Confirm whether your homeowner policy covers storm surge and flood (3) Identify your nearest shelter above the flood zone

Midcoast and Downeast (Sagadahoc through Washington counties)

The working coast: fishing communities, island populations accessible only by ferry, and long stretches of exposed shoreline. Washington County, Maine's most rural coastal county, faces both Atlantic storm exposure and extreme isolation. Island communities can be cut off for days when ferry service suspends during storms.

Hazards requiring added attention: Coastal storm surge, island isolation, extended power outage, nor'easter wind damage, ice storms

Likely complications: Ferry suspension, single-road access to peninsulas, limited emergency services in remote areas, seasonal population fluctuation

Three local verification tasks: (1) Confirm your alternate route if your primary road floods or is blocked (2) If on an island, verify winter ferry schedule and emergency protocols (3) Know the location of your nearest hospital and whether it has 24-hour emergency services

Kennebec and Androscoggin River Valleys

The central corridor including Augusta, Lewiston-Auburn, and the communities along the Kennebec and Androscoggin rivers. This region faces regular spring flooding from snowmelt, ice dam formation, and runoff from the western mountains. The 1987 flood and the 2024 January storms demonstrated how quickly these rivers can exceed their banks.

Hazards requiring added attention: Riverine flooding, ice jams, spring snowmelt flooding, severe thunderstorms, ice storms

Likely complications: Bridge closures, basement flooding in river-adjacent neighborhoods, municipal water treatment disruption during high turbidity

Three local verification tasks: (1) Check whether your property or travel routes cross a mapped 100-year flood zone (2) Know the flood stage for your nearest river gauge (3) Identify a route to high ground that does not cross a bridge over water

Western Mountains (Oxford and Franklin counties)

The mountainous interior, including the Rangeley Lakes, Sugarloaf, and Sunday River areas. Heavy snowfall (200+ inches in some years at elevation), steep terrain, and limited road networks define the risk profile. Ice storms and heavy wet snow collapse trees across power lines. Mountain passes and notches can close during storms.

Hazards requiring added attention: Heavy snowfall, ice storms, extreme cold, flash flooding on steep terrain, wildfire (spring dry season)

Likely complications: Road closures on mountain passes, extended power outages in areas served by long feeder lines, limited cell service in valleys

Three local verification tasks: (1) Confirm that your driveway and access road can be cleared by your own equipment or a contracted plow (2) Test your backup heating system before November (3) Verify cell service reliability from your property and identify the nearest landline or alternative

Central Highlands (Somerset and Piscataquis counties)

Maine's most sparsely populated interior, including Moosehead Lake, Baxter State Park, and much of the North Maine Woods. Many roads are private logging roads, and some communities are accessible only by seasonal roads. Emergency services may be 30 to 60 minutes away. Extended self-reliance is not optional; it is the baseline condition.

Hazards requiring added attention: Extreme cold, extended power outages, ice storms, spring flooding, wildfire in remote forestland

Likely complications: Long emergency response times, private road maintenance interruptions, limited supply points, seasonal road closures

Three local verification tasks: (1) Confirm whether your access road is publicly or privately maintained and who plows it (2) Identify your nearest year-round supply point for fuel and food (3) Verify that your address is registered with 911 dispatch

Aroostook County (The County)

The largest county east of the Mississippi, covering more land area than Connecticut and Rhode Island combined. Aroostook experiences some of the coldest temperatures in the lower 48 states. The Canadian border creates unique logistics: supply chains, medical facilities, and mutual aid agreements cross international boundaries. Farming communities face spring flooding on the St. John, Fish, and Aroostook rivers.

Hazards requiring added attention: Extreme cold (temperatures to -40°F, wind chills to -60°F in severe events), heavy snowfall, spring flooding on northern rivers, ice storms, extended isolation

Likely complications: Heating fuel delivery delays, cross-border supply chain sensitivity, long distances to tertiary medical care, limited alternate routes

Three local verification tasks: (1) Calculate your heating fuel reserve in days and weeks, not just gallons (2) Identify whether your nearest hospital is in Maine or across the border in New Brunswick (3) Know the flood stage for your nearest river and whether spring breakup flooding has reached your property historically

Seasonal readiness

A Maine household readiness calendar.

Maine's hazard profile has a strong seasonal rhythm. This calendar identifies the higher-attention periods and the household tasks that match them. A hazard occurring outside its typical season is unusual but not impossible.

Maine seasonal readiness calendar
Season / Period Typical hazard activity Household readiness task
October Nor'easters begin; first hard frosts; coastal storm risk increases Test backup heat. Schedule heating fuel delivery. Winterize pipes. Check storm windows and weatherstripping. Review insurance coverage.
November - December Ice storms, heavy snow, nor'easters, extreme cold begins in the north Confirm snow removal arrangements. Stock emergency water. Check battery supply for lights, radio, and phone charging. Verify furnace maintenance.
January - February Peak ice storm and extreme cold period. Longest outage potential. Major nor'easters. Monitor fuel levels weekly. Keep vehicles above half tank. Check roof load after heavy snow events. Inspect for ice dams. Maintain clear egress from all doors.
March - April Spring snowmelt flooding. Late-season nor'easters. Ice jam formation on rivers. Monitor river gauges if near a floodplain. Check sump pump and backup battery. Clear drainage around foundation. Watch for road washouts on seasonal roads.
May - June Spring wildfire season (dry conditions before green-up). Severe thunderstorms begin. Flood risk from heavy rain on saturated ground. Clear brush and debris from around structures. Check smoke and CO detectors. Review wildfire defensible space. Inspect emergency water supply for quality.
July - August Severe thunderstorms. Drought risk peaks. Tropical cyclone remnants (late August). Air quality impacts from regional wildfire smoke. Monitor well levels during dry spells. Conserve water early if drought develops. Review hurricane and coastal flood preparations. Check air quality during smoke events.
September Peak tropical remnant risk. Late-season drought. Transition to fall storm season. Begin pre-winter preparations. Schedule chimney cleaning if burning wood. Review emergency supplies and replace expired items. Update medication list.

Cascading disruptions

How one failure leads to the next.

Single hazards rarely cause the worst household outcomes. The combination of failures does. These chains are characteristic of Maine's geography, infrastructure, and winter climate.

Ice storm → tree collapse on transmission lines → extended power outage → electric well pump failure → no water → no flush sanitation

The 1998 ice storm demonstrated this chain across half the state. Households with backup heating survived comfortably; those without were evacuated. The water loss is often the forcing function, not the cold itself. A household with a generator, a gravity-fed spring, or stored water breaks the chain at step four.

Nor'easter → storm surge + astronomical high tide → coastal road flooding → evacuation → saltwater intrusion into coastal wells → contaminated drinking water for weeks

Southern coastal communities face this chain when a storm coincides with spring tides. The saltwater intrusion outlasts the storm by weeks or months. Flushing a salt-contaminated well requires repeated pumping and testing. Stored drinking water and an alternate supply plan break the chain.

Spring snowmelt → river flooding → road and bridge washout → community isolation → delayed emergency response → supply delivery failure

Rural communities with single-road access are most vulnerable. The 2008 spring floods on the St. John and Aroostook rivers evacuated over 600 people. Knowing your alternate route and maintaining a food and fuel reserve reduces the consequence of isolation.

Extreme cold → heating system failure → pipe freezing → pipe burst → water damage → uninhabitable home in freezing conditions

This chain runs in hours, not days. Once pipes freeze and burst, the damage compounds rapidly when temperatures eventually rise. Keeping heat above 55°F in all occupied spaces, insulating vulnerable pipes, and knowing how to shut off your main water valve are the critical interventions.

Power outage → generator use indoors or in attached garage → carbon monoxide poisoning

Multiple fatalities in the 1998 and 2008 ice storms resulted from generator misuse. A generator must run outdoors, at least 20 feet from any window, door, or vent, with exhaust directed away from the structure. Working CO detectors with battery backup are not optional. This chain is entirely preventable.

Household situations

What changes for your household.

The same hazard hits different households differently. These modules identify what changes for specific situations and where to start.

Renters and apartment residents

You may not control the building's heating system, generator, or emergency exits. Verify: Does the landlord have a backup heat plan? Are there working smoke and CO detectors in your unit? Where is the nearest shelter if the building loses heat? Renter's insurance covers personal property that homeowner policies do not.

Manufactured-home residents

Manufactured homes are more vulnerable to wind damage and less insulated against extreme cold than site-built structures. Verify that tie-downs meet current standards. Identify the nearest substantial shelter for high-wind events. Insulate skirting and exposed water lines before winter.

Rural private-well households

Every power outage is a water outage unless you have backup pumping. Know your well depth, static water level, and pump rating. Options include a generator with a transfer switch, a hand pump, or a gravity-fed system. Store water for the gap between outage and backup activation.

Electric-only heat or cooking

If your only heating source requires electricity, you have no heat during an outage. This is Maine's most dangerous single dependency. Options: a wood stove with a proper chimney, a propane space heater rated for indoor use with ventilation, or a generator sized to run the heating system.

Older adults and people living alone

Establish a check-in arrangement with a neighbor, family member, or community organization before an event. Hypothermia risk increases with age. If you cannot safely operate a generator or alternative heating, identify a warming shelter or host household in advance.

Medically dependent households

If someone in your household depends on powered medical equipment (oxygen concentrator, CPAP, dialysis, infusion pump), register with your utility company's life-support or medical priority list. Have a backup power source tested and ready. Maintain a current medication list and know the nearest alternate care facility.

Households without vehicles

Rural Maine has limited public transportation. If you do not have a vehicle, identify a neighbor, community organization, or municipal resource for emergency transportation. Keep a larger food and water reserve since you cannot drive to resupply. Know whether your town provides emergency rides to shelters or medical facilities.

Coastal property owners

Review storm surge and sea-level-rise inundation maps from the Maine Geological Survey. Standard homeowner policies do not cover flood damage; flood insurance through the NFIP is separate. Salt spray, erosion, and rising groundwater are gradual risks that affect property value and well water quality over years, not just during storms.

Warning systems

How warnings reach your household.

Maine's warning chain runs from federal detection to your household decision. Knowing each layer helps you understand what kind of notice you will get and what it means.

Federal detection and forecast: NWS forecast offices in Caribou (CAR) and Gray/Portland (GYX) monitor weather, issue watches and warnings, and provide river and coastal flood forecasts for all of Maine. The Northeast River Forecast Center (NERFC) provides river-stage forecasts.

Wireless Emergency Alerts (WEA): Sent directly to cell phones in the affected area for tornado warnings, flash flood warnings, extreme wind warnings, and other imminent threats. No enrollment required, but your phone must be on and in range of a cell tower.

NOAA Weather Radio: Continuous broadcasts from NWS transmitters. Coverage includes most of Maine but some mountain valleys and remote areas have gaps. A weather radio with battery backup and alarm tone activation provides 24-hour monitoring even during power outages and cell service failures.

County and municipal alert systems: Many Maine counties and municipalities operate opt-in notification systems (Code Red, Everbridge, Nixle, or similar). These provide location-specific alerts by phone, text, and email. You must enroll; they are not automatic. Contact your county EMA for enrollment information.

State emergency communication: MEMA coordinates statewide emergency information through its website, social media, and the Maine.gov subscription service. During major events, MEMA activates the State Emergency Operations Center (SEOC) and provides regular situation reports.

Understanding the alert levels

Outlook: Conditions may develop. No immediate action needed; monitor updates.

Watch: Conditions are possible. Review your plan, prepare to act.

Warning: Conditions are occurring or imminent. Take protective action now.

Evacuation order: Leave the area immediately by the designated route. An evacuation order from local officials overrides general preparedness guidance.

Shelter instruction: Take shelter in the safest available location. Do not attempt to travel.

Recovery information: Wait for official all-clear before returning to an evacuated area. Check for damage and hazards before entering structures.

Prepare, endure, recover

The three phases of household readiness.

Prepare

Actions you can complete before the higher-attention season or within the next month:

  • Test your backup heating system and confirm fuel supply lasts at least two weeks without resupply
  • Store drinking water: one gallon per person per day for at least three days, more if you depend on an electric well pump
  • Enroll in your county's alert notification system and confirm NOAA Weather Radio reception at your home
  • Identify your home's lowest interior room for severe weather shelter
  • Assemble or update your emergency documents: insurance policies, medication list, identification, and household contacts
  • Winterize pipes, especially in crawl spaces, unheated garages, and exterior walls
  • Clear drainage around your foundation and test your sump pump backup battery
  • If on the coast, review flood insurance and confirm it is active before storm season
  • Identify two routes to your nearest hospital, pharmacy, and supply point
  • If you burn wood, schedule chimney cleaning and inspect the stovepipe and clearances

Endure

Household continuity decisions during the disruption:

  • Monitor official sources for your area: NWS, MEMA, county EMA, and local public safety
  • If you lose power and heat simultaneously, consolidate the household into the smallest room you can keep warm
  • Never operate a generator, grill, or camp stove indoors or in an attached garage. Generators belong outdoors, at least 20 feet from any window, door, or vent, with exhaust directed away from the structure
  • If roads are impassable, stay put. Most injuries during winter storms occur in vehicles, not homes
  • Keep refrigerator and freezer doors closed to preserve food temperature: a closed freezer holds safe temperatures for roughly 48 hours if full, 24 hours if half-full
  • Check on neighbors, especially those living alone, elderly, or medically dependent
  • If you smell gas or suspect a CO leak, leave the building immediately, do not operate electrical switches, and call 911 from outside
  • For flooding: do not walk or drive through moving water. Six inches of moving water can knock a person down; one foot can carry a vehicle

Recover

First recovery steps after the event:

  • Wait for official all-clear before returning to an evacuated area or entering a damaged structure
  • Document damage with photos and written descriptions before making repairs. Contact your insurance company promptly.
  • If your home was flooded, watch for structural damage, mold, and contaminated wells. Do not use well water until tested
  • After a power outage, check food safety: discard any perishable food held above 40°F for more than two hours
  • Be cautious with contractors. After a declared disaster, the Maine Attorney General's office publishes guidance on avoiding storm-chasing fraud
  • If a federal disaster is declared, FEMA Individual Assistance may be available. Apply at DisasterAssistance.gov or call 1-800-621-3362
  • Call 211 (available statewide through 211 Maine) for local recovery resources including food, shelter, heating assistance, and mental health support

Ten-action checklist

Ten high-value actions for Maine households.

1

Identify whether your NWS forecast office is Caribou or Gray/Portland, and enroll in your county's emergency alert system.

2

Establish and test a backup heating method that works without grid electricity before November.

3

Store at least three days of drinking water. If you rely on an electric well pump, store more and identify a backup pumping or water-supply method.

4

Check whether your home and two ordinary travel routes cross a mapped flood hazard area using the FEMA Flood Map Service Center.

5

Install or verify working CO detectors with battery backup on every level of your home, especially near bedrooms and any fuel-burning appliance.

6

Keep a current medication list and copies of critical documents (insurance, identification, prescriptions) in a waterproof container you can take with you.

7

If you live on the coast, review the Maine Geological Survey sea-level-rise and storm surge inundation maps for your property.

8

Insulate exposed water pipes in crawl spaces, unheated garages, and exterior walls. Know the location of your main water shutoff valve.

9

Agree on a household communication and reunification plan, including an out-of-state contact and a meeting point if family members are separated.

10

Maintain backup lighting (headlamps, lanterns with extra batteries) and at least one method to charge a phone that does not require grid power.

Earthquake information

What Maine has learned

The 1998 ice storm lesson: backup heat is not optional.

In January 1998, freezing rain fell across Maine for three consecutive days. Ice accumulated on the state's heavily forested landscape, snapping trees and collapsing utility lines across vast areas. More than half of Maine's population lost power. All 16 counties were declared federal disaster areas (FEMA DR-1198). Some households went without electricity for up to three weeks. It took 23 days to fully restore power statewide.

The storm cost the state an estimated $320 million and led to multiple fatalities, including deaths from carbon monoxide poisoning when people ran generators indoors or in attached garages. Approximately 18,000 miles of power lines came down.

The household decision that mattered most was simple: households with backup heat that did not depend on electricity stayed warm. Households without it were evacuated or endured dangerous cold. The 1998 storm established the principle that still defines Maine household preparedness: in a state where winter outages are structural rather than exceptional, backup heating independent of the grid is the single most consequential preparation a Maine household can make.

Limits and methodology

What this page can and cannot tell you.

This page provides statewide and regional awareness. It cannot determine your property-level risk, which depends on your specific location, elevation, soil conditions, proximity to water, building construction, access roads, and surrounding terrain. A professional site evaluation or your county's local hazard mitigation plan will address property-specific questions.

Historical frequency is not a forecast. A hazard that has not occurred recently can still occur, and a hazard that occurred recently may not repeat on the same schedule. Maps and designations change as new data becomes available, flood maps are updated, and land use changes.

During an active event, official instructions from local emergency management, law enforcement, fire departments, and the NWS supersede general preparedness guidance on this or any other page.

Hazard selection and emphasis are based on the 2023 Maine State Hazard Mitigation Plan, FEMA disaster declaration history, NWS event data, and the Maine Geological Survey. Regions are organized by shared hazard exposure and infrastructure characteristics. This page does not assign risk scores or use proprietary ranking methods.

Common questions

Maine local risk, answered.

What are the most consequential hazards for Maine households?

Ice storms, nor'easters, extended power outages, extreme cold, riverine and flash flooding, and coastal storm surge. The 2023 State Hazard Mitigation Plan classifies flooding, severe fall and winter weather, severe summer weather, and wildfire as Tier 1 hazards. Which hazards matter most depends on where in Maine you live: coastal communities face storm surge and erosion, northern and interior areas face extreme cold and isolation, and the heavily forested landscape makes extended power outages a statewide structural condition.

How do I find my NWS forecast office and county emergency management in Maine?

Maine is served by two NWS forecast offices: Caribou covers northern and eastern zones, and Gray/Portland covers southern and western zones plus New Hampshire. Enter your address at weather.gov to confirm which office issues warnings for your area. For county emergency management, visit the Maine Emergency Management Agency (MEMA) website for a directory of all 16 county EMA offices. Enroll in your county's alert notification system for location-specific warnings.

What causes the longest power outages in Maine?

Ice storms cause Maine's longest outages. The January 1998 ice storm left approximately half the state without power, with some areas dark for up to three weeks. All 16 counties were declared federal disaster areas (FEMA DR-1198). The state's heavily forested landscape and long rural transmission lines make extended outages a structural hazard, not a rare event. A household that depends on electric heat, well water, or refrigerated medication needs backup systems that work without grid power.

Is wildfire a real risk in Maine?

Yes, though the current risk is modest in most years. Maine is approximately 89 percent forested, covering about 17.5 million acres. The Maine Forest Service reports an average of about 600 fires burning roughly 500 acres per year in recent times. The 1947 fires burned more than 220,000 acres and destroyed over 1,000 homes. The 2023 State Hazard Mitigation Plan classifies wildfire as a Tier 1 hazard. Conditions in eastern Canada in 2023, when wildfire smoke blanketed Maine for much of the summer, demonstrated that the risk extends beyond direct fire to include air quality and evacuation planning.

What should every Maine household do first to prepare?

Identify your NWS forecast office (Caribou or Gray/Portland) and enroll in your county's alert system. Establish backup heat that works without electricity and test it before winter. Store at least three days of drinking water, more if you rely on an electric well pump. Keep a current medication list and copies of critical documents in a portable location. Check whether your home or regular travel routes cross a mapped flood hazard area. If you live on the coast, review storm surge and sea-level-rise maps from the Maine Geological Survey.
